Question

Proszę o obliczenie tych ułamków zwykłych

Answer 1

4 1/2 + 3/1 * 17/4 = 4 1/2 + 51/4 = 4 1/2 + 12 3/4 = 4 2/4 + 12 3/4 = 17 1/4

2 1/4 * - 4 1/5 9/4*3/1-4 1/5 6 3/4-4 1/5
--------------- = --------------- = --------------- =
1/4 1/4 1/4

9/4*3/1-4 1/5 6 3/4-4 1/5 6 15/20-4 4/20
--------------- = -------------- = ------------------ =
1/4 1/4 1/4

= 2 11/20 : 1/4 = 51/20*4/1=51/5= 10 1/5

1 1/4 - 1/3 = 1 3/12- 4/12= 1 7/12

2/9*5/1=10/9=1 1/9

6*1 3/5=6/1*8/5=48/5=9 3/5

3 5/12*3=41/12*3/1=10 1/4

1/5:2/3=1/5*3/2=3/10

2 1/5*1 2/3= 11/5*5/3=3 2/3

Myślę, że pomogłam i licze na naj ;*
